Dear sir,

I am trying to do impact analysis of a ball on ip for which i am getting internal energy at high peak from start of the run as shown in the figure, though i used ELFORM 24 (UNDER INTEGRATED WITH HOUR GLASS STABILIZATION) H.G Energy seems to be high and more over there is no energy transfer being happened after the impact can you help me with this?\

Anticipating a positive quick response.

    Hi Ramakiran,

    Which solver are you using?.

    Instead of under integrated elements please run with fully integrated element formulation and review the results.

    Hi Ramakiran,

    For shell elements use Ishell=24, N=5, run the analysis and review the results.

    For solid components also you have assigned shell property in the model file which you have sent me. Please correct them and use the above options.
